The goal of freeze drying is to dry samples as gently as possible. The physical principle of sublimation is used to let ice turn directly into a gaseous state without melting water forming. Vacuum plays a key role here, as sublimation is only possible under exact pressure conditions.

In this webinar, our VACUUBRAND expert explains why precise vacuum is crucial in this application and why too low pressure is counterproductive. You will also receive valuable advice on how to not only achieve optimum results and process times, but also how to effectively protect your vacuum pump from wear.
